ROBERT W. IBLAISDELL, OF MILVIAUKEE, WISCONSIN.

MULTITOOL SHOE-WORKING MACHINE.

Application filed February 3, 1916.

To all whom it may concern:

Be it known that I, Ronnnr W. BLAISDELL, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Multitool Shoe-Working Machines; and I do hereby declare that the following is a full, clear, and exact description thereof.

The present invention relates to new and useful improvements in shoe working machines, more particularly of that type involving a plurality of tool members for procuring finishing operations.

It is the present practice to provide a machine for various shoe finishing operations which comprises a relatively long lathe body carrying a plurality of shafts on each of which is positioned one or more shoe working tools and this form of machine necessitates a considerably complicated and conse-' quently expensive structure which, on account of its size and expense is not adapted for use in small shops.

It is the object of the present invention to provide a structure wherein all of the opera tions of the usual lathe of this type may be procured with a maximum simplicity and compactness of structure, and to this end it is more particularly the object to provide a structure which is adapted for the association of the various tool members with a single spindle head.

A further object resides in the provision of a bearing member for use with those certain types of tool members which include a relatively long hub portion, and which is so mounted as to not interfere with the use of tools in which there is no necessity for a bearing member.

\Vith the above and other objects and advantages in view, the invention resides more particularly in the novel combination, arrangement and formation of parts hereinafter described and pointed out in the appended claim.

In the drawings:

Figure 1 is a front elevation of the improved machine showing a heel trimming tool associated with the spindle thereof, this tool being in section to illustrate the disassembling feature thereof to facilitate re moval and insertion of the blade members.

Fig. 2 is an end view of the improved machine, with a portion of the structure adjacent the tool member broken away.

Specification of Letters Patent.

Patented Aug. 1%, 1917.

Serial No. 75,930.

Fig. 3 is an elevational view of the detachable edge trimming tool member of the lathe.

Fig. 4 is an elevational view of the buffer roll member of the lathe.

Fig. 5 is an elevation of the heel breastscourer member.

Fig. 6 is a similar view of the bottom staining brush member.

Fig. 7 is a similar view of the felt heel breast scourer member.

Fig. 8 is a similar view of the edge burnishing roll member.

Fig. 9 is a similar view of the bottom burnishing roll member.

Referring now more particularly to the accompanying drawings, my improved machine comprises a body standard 5 which has its lower end bifurcated to provide spaced bearings for a main drive shaft, which also has a bearing in an upstanding bracket 7 on the base 8 of the standard, suitable bearing pulleys 9 being provided on the shaft for coaction with a suitable source of power. The upper end of the standard is also bifurcated to provide spaced bearings 10 for the spindle head shaft 11, a pulley 12 being provided on the shaft between the furcations and carrying a belt 13 which is driven by a relatively large pulley 14 disposed on the driveshaft 6 between the lower furcations of the standard. The spindle head shaft 11 also carries between the upper standard furcations a hand brake wheel 15 and a pulley 16 adapted to carry a belt member for driving auxiliary machinery if desired.

Secured to the intermediate portion of one side of the standard 1s a fan casing 17, the shaft of which is parallel to the main drive shaft and is driven therefrom. by a belt 18 trained around pulleys 19 on the fan and drive shafts. Extending upwardly from this fan casing is an air duct 20 having its upper end fiaringly enlarged to form a hood 21 disposed at one end of the spindle shaft, this end of the spindle shaft being hereinafter termed the head end thereof and being pro vided with a threaded socket 22 in which is engageable threaded pintles of the various tools.

Certain tools used in the present connection are relatively long and require a bearing at their end farthest from the spindle head, but certain other types of tools are relatively short and the provision of a bearing adjacent their end farthest from the spindle head would interfere with proper operation in connection with such tools even though. the bearings would not operatively coact with such tools and to adapt the present structure for use in connection with all types of tools used in the present connecperend of which is formed the bearing 26.

The sleeve is adapted to be locked on the shaft 23 by a suitable set screw 24:, and when the sleeve is unlocked, with respect to the shaft, the bearing 26 may be moved toward or away from the spindle 11 ormay be swungto hang downwardly in a position not interfering with operations adjacent the spindle head. If desired, the entire bearing structure including the shaft 23 may be readily detached from the machine.

Taking up now the heel trimming tool lnember which is illustrated in Fig. 1, in section, said tool member comprises a shaft 27 connected with the head of the spindle shaft in the usual manner heretofore described and engaging at its outer end in the bearing 26. Carried on the shaft is a fixed plate 28 and a slidable plate 29, the opposite faces of these plates being provided with oppositely alined pairs of sockets 30 each adapted to receive the ends of a respective trimming blade and the plates are held in certain spaced relation to hold the blades for operation, by anut 31threaded on the shaft and bearing against the outer face of the plate 29, thus by retracting the nut 31 the plates may be moved apart to permit the insertion of blades of different shape or of sharpened blades, without necessitating the detachment of the tool member from the machine.

In attaching the tool member, its shaftis first connected with the shaft 11 and then the bearing 26 is disposed on its outer end and the binding screw 24: is rotated to bind the sleeve 24: in a rigid position. In detach- Gopies of this patent may be obtained for fivecents each, by addressing the Washington, D. C.

ing the tool member, the bearing 26 is first removed therefrom and the tool shaft then detached from the spindle head shaft.

Fig. i illustates a buffer roll member which is attached or detached in a similar manner, the roller body 32 having at one end the threaded pintle 33 for engagement in the socket'22 of the spindle head, and

having at its other end the bearing pintle 3% for engagementin the bearing 26.

In Fig. 5 wherein is shown the heel breast scourer member, the attachment of a 'tool member shaft to'the spindle head is more particularly illustrated, this structure including a wheel'35 carried on-a'shaft 36 one end-of which is reduced to form the usual threaded pintle portion 37 engaging in the spindle shaft head, which is here shown in section.

Figs. 3, 5,6, 7, *8,-and9 designate other conventional tool members, each of which carries a respective pintle 38 :forengagement in the socket ofthe spindle head.

A machine is thus provided which comprises a single pintle shaft-member with which may be HSSOCIMJGClZLIlY of the tools commonly used in the present 5 connection, and wherem such toolsmay be mounted for their most efiicient operations.

I claim: 1

In a 'machine of the class described the combination ofan lip-standing standard, a spindle journaled in the upper portion of the standard, a toolincluding a spindle portion constructed at one end for detachable ROBERT W. BLAI-SDELL.
